Ken Roczen and Marvin Musquin Prepping For Seattle

Ken Roczen will race the Supercross class aboard a KTM 350SX-F in Seattle. "For me, it is just for fun," he said. "I did some races on it last year, but today is my first day on the 350 on a Supercross track, this year."

Marvin Musquin, meanwhile, is anxious to get back to racing the Western Regional Supercross Lites Championship, which resumes in Seattle. "This is my first day of Supercross since Toronto," said the former MX2 World Champion, who raced the 350SX-F for several rounds. "I am excited to be back on my 250!"
